Predicate: Stryker MEDPOR Customized Implant– K143173 This predicate has not been subject to a design-related recall. ### IV. DEVICE DESCRIPTION {4}------------------------------------------------ The Stryker CMF MEDPOR Customized Implant (CI) product offerings provide customized craniofacial patient specific implants designed at the request of a surgeon. The customized craniofacial implants are molded from porous high density polyethylene (HDPE) and the MEDPOR material provides a porous structure which allows for tissue ingrowth. The MEDPOR CI is manufactured to the specific reconstruction boundaries indicated by the surgeon via submission of CT scans and a customized implant request. This traditional 510(k) is submitted to add an additional indication for use for the augmentation and/or restoration of ... soft tissue deformities in the cranial and craniofacial skeleton; including but not limited to, the correction and prevention of persistent temporal hollowing (PTH). #### V. INDICATIONS FOR USE The Stryker CMF MEDPOR Customized Implant is indicated for the augmentation and/or restoration of bony and/or soft tissue deformities in post-traumatic, post-surgical, or congenital craniofacial defects; including but not limited to, the correction and prevention of persistent temporal hollowing (PTH). The MEDPOR CI PLUS has an additional indication for use which is not included in the Predicate device an added PLUS design option, but this difference does not constitute a new Intended Use. Both the MEDPOR CI PLUS and the predicate device have the same Intended Use to fill bony voids, defects, and contour irregularities in non-load bearing regions of the cranial skeleton. Also, this difference does not alter the intended therapeutic use of the device nor does the difference affect the safety and effectiveness of the device relative to the predicate device. A literature review was performed to identify relevant clinical literature with applicable data to show that, when compared to the predicate device, the new Indication for use added to the subject device does not raise new questions of safety or effectiveness. The results of this review provides evidence of this fact. #### VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE The MEDPOR CI PLUS is compared to its predicate device for substantial equivalence based on the following criteria: - A. Principle of Operation - B. Technological Characteristics The only changes associated with the subject device design, relative to the predicate device, result from the additional indication for use. The additional indication for use corresponds to {5}------------------------------------------------ Image /page/5/Picture/0 description: The image shows the Stryker logo in black. The logo is a stylized wordmark with a unique font. The letters are bold and have rounded edges. The registered trademark symbol is located in the upper right corner of the logo. a contour design selection option during the ordering process, and enhanced surgeon input during the design process. The remaining technological characteristics of the subject device, when compared to the predicate device, are unchanged. ### A. Principle of Operation The basic operational principle of the MEDPOR CI PLUS remains the same as the predicate: the MEDPOR Customized Implant is intended to be used to fill bony voids, defects, and contour irregularities in non-load bearing regions of the cranial skeleton. ### B. Technological and Operational Characteristics The addition of a new indication for use to the MEDPOR CI does not alter the technological characteristics of the actual customized cranial or craniofacial implant. The technological characteristics remain the same as the predicate: - Same operating principle: to fill bony voids, defects, and contour irregularities in non-load bearing regions of the cranial skeleton. - Same mode of fixation: fixated to the native bone with Stryker Neuro, Midface, and, or, Upperface self-drilling screws. - -Same material: Implants are made from high density polyethylene (HDPE). - Same design: the customized craniofacial implants are molded from HDPE to the specific reconstruction boundaries indicated by the surgeon via submission of CT scans and a customized implant request. ### VII. PERFORMANCE DATA ### Biocompatibility Testing Biocompatibility and sterility testing of the device is not required as a basis for substantial equivalence. There is no change in the material, duration or location of contact, or sterilization methods for the MEDPOR CI PLUS. The identical manufacturing processes and materials are used in both the subject and predicate device. ### Performance Bench Testing Performance Bench testing was not required as a basis for substantial equivalence. ### Animal Testing Animal testing was not required as a basis for substantial equivalence. ### Clinical Testing {6}------------------------------------------------ To support the inclusion of the PLUS design option, and the corresponding indication for use, Stryker has leveraged clinical literature and case history. A summary of the clinical literature verifies that PTH reflects a deficiency in the bulk of the temporalis muscle or overlying temporal fat pad. Surgical results with augmented implant designs have been published upon and shown to be clinically successful in addressing PTH. To that end, Stryker has incorporated surgeon design input into a customized implant with an augmented contour. In all patient-specific reconstructions, the level of implant augmentation may be adjusted based on surgeon clinical knowledge of the patient condition and the surgical approach. This culmination of surgeon input and approval and case history results in the CI PLUS, which has shown that the augmented contour of the CI PLUS counteracts the asymmetry observed in certain neurosurgical procedures. ### VIII. CONCLUSIONS According to the comparison based on the requirements of 21 CFR 807.87 and the information provided herein, it is concluded that the information included in this submission supports substantial equivalence.
